A straw bale infill post and beam structure was the new format for the workshop in 2009. It was built in Sonoma county and will become a guest cottage and/or art studio for the owners. Bob Theis designed it and led the bale raising workshop. The structure used peeled poles from the site and will have a living roof. Tracy Thieriot led the Earth Plaster workshop with assist from Bob and Emily Reynolds (trained in Japan to make and apply Natural plasters).
